This may be a silly question, but I've been looking for information about deploying a Swift backend to hosting services like Heroku without using the Vapor framework. Are frameworks like Vapor necessary for Swift server projects? as I use (and prefer) a lower-level library for WebSockets that is (imo) easier than implementing in Vapor.
I guess the question is, how to deploy a command-line-tool to the server without Vapor.
Thanks.
